View source for SDR Satcom App Store

== Introduction ==

The SDR Satcom app store makes it easy to distribute and install software-defined radio (SDR) applications for satellite communications (satcom).

The app store is provided as part of a wider initiative supported by the [https://www.esa.int European Space Agency] in partnership with [https://limemicro.com Lime Microsystems], that is dedicated to:

* democratising access to enabling hardware platforms
* fostering open source SDR development
* accelerating the pace of satcom innovation

== Requirements ==

Applications are distributed as containerised ''snaps'' which neatly package them together with their dependencies, thereby simultenously simplifying the installation of complex software stacks and the task of supporting a wide variety of Linux distributions and versions.

For details of the supported Linux distros, see [https://docs.snapcraft.io/installing-snapd/6735 Installing snapd].

== Accessing ==

To install snaps you need to:

# Have snapd and tools available
# Configure snapd to use the SDR_Satcom store

=== snapd ===

The snapd daemon and tools are used to provide support for snaps.

Snap support comes pre-installed with classic Ubuntu version 16.04.4 and upwards. It is also the native packaging system for [https://www.ubuntu.com/core Ubuntu Core].

Solus 3 and Zorin OS also provide out-of-the-box support for installing snaps, while [https://docs.snapcraft.io/installing-snapd/6735 installation instructions] are provided for Arch, CentOS, Debian, Raspbian and many others.

=== Configuration ===

Configuring snapd to use the SDR_Satcom store is simple:

<source lang="bash" line='line'>
echo "UBUNTU_STORE_ID=SDR_Satcom" | sudo tee -a /etc/environment
sudo service snapd restart
</source>

=== Basic use ===

To search for a snap with a name containing "lime":

<source lang="bash" line='line'>
snap search lime
</source>

To install sathelperapp:

<source lang="bash" line='line'>
sudo snap install sathelperapp
</source>

Snaps which access a LimeSDR board, or integrated transceiver of a LimeNET Micro or CrowdCell, will also need the ''raw-usb'' interface connecting. For example, with sathelperapp:

<source lang="bash" line='line'>
sudo snap connect sathelperapp:raw-usb
</source>

For further details see the [https://docs.snapcraft.io/snap-documentation/3781 Snap Documentation].
